In 1979, Richard Stanley made the following conjecture: Every Cohen-Macaulay simplicial complex is partitionable. Motivated by questions in the theory of face numbers of complexes, the conjecture sought to bridge a combinatorial condition and an algebraic condition. Recent work of the speaker and collaborators resolves the conjecture in the negative. I will discuss the history and context of the conjecture, the counterexamples, the consequences, and the new questions we are now asking.
